SPECIFICATION forming part of Letters Patent No. 613,935, dated.November 8, 1898.

Application filed. December 28, 1897- Serial NO- 6631933. (No model.)

To all whom it may concern.-

Be it known that I, TOM NORTON, a subject of the Queen of GreatBritain,residing at New= town, in the county of Montgomery, Wales,England, have invented a new and useful Im provement in the Frames ofVelocipedes, (for which I have obtained Letters Patent of Great Britain,No. 5,676, bearing date the 13th of March, 1896,) of which the followingis a full and complete specification.

This invention relates to an improved frame for rear-driving bicyclesand some types of tricycles and other Velocipedes; and it consists,essentially, in the use of a double diagonal, the object being to obtaina strong and rigid frame of the open type suitable for the use ofladies.

In the frames of cycles for the use of ladies it is usual to dispensewith the top member of the ordinary diamond frame and to strengthen thefront part of the said frame, which then only consists of the diagonalmember and the member extending between the pedal-crankaxle bracket andthe socket of the steeringhead, by means of another member placed overthe aforesaid member extending between the pedal-crank-axle bracket andthe socket of the steering-head, which auxiliary member is sometimesstraight and sometimes curved. Now according to my invention I duplicatethe member known as the diagonal, extending upward from thepedal-crank-axle bracket and usually employed to carry the seat-pillar,and I brace the points of junction of this auxiliary diagonal to theother members by one or more suitable pieces arranged in any convenientmanner.

In the accompanying drawings, which show illustrated in the accompanyingdrawings. The arrangement of these members, however, forms no part ofthis invention.

D designates the members of the lower back fork, and E the members ofthe upper back fork, forming together the rear part of the frame adaptedto receive the driving-wheel, and X designates the auxiliary diagonal,form ing the subject of this invention. This aux= iliary diagonal mayeither extend past the member 0 and join the member 0, as shown byFigure 1, or it may stop at the member O, as shown by Fig. 3. When itextends beyond the member 0 and joins the member O, the

member 0 may stop at the auxiliary diagonal X, as shown by Fig. 2.

It will be obvious that this invention may be applied to either thefront or the back part of a tandem bicycle or to both parts. Itsapplication to the front part will be apparent from Figs. 1, 2, 3, and4:, showing its application to a single bicycle, while one method ofapplying it to boththe front and the rear part of a tandem is shown byFig. 5.

What I claim, and desire to secure by Let ters Patent, is- 1 In a framefor bicycles and-other velocipedes, the combination with the socket A ofthe steering-head, of a member 0 connecting the said socket with thepedal-crank-axle bracket, of a diagonal member B extending upward fromthe pedal-crank-axle bracket to carry the seat-pillar, of an auxiliarymember 0 connecting the socket A of the steeringhead with the lower partof the diagonal memberB, of members D extending rearward from the pedalcrank axle bracket forming the lower back fork, of members E connectingthe rear ends of the lower back fork with the upper ends of the diagonalmember B forming the upper back fork and of an auxiliary diagonal memberX connecting the upper end of the diagonal member B with the auxiliarymember 0 adjacent to the pedal-crank-axle bracket, as and for thepurpose set forth.
